The **small swirlprismatic pyrihecatonicosihexacosichoron** or **gisp pydixhi** is a scaliform polychoron. It consists of 600 triangular prisms, 120 pentagonal prisms, and 240 pentagrammic pyramids (falling into pairs in the same hyperplanes, forming 120 compounds of 2). Thirty triangular prisms, ten pentagonal prisms, and twelve pentagrammic pyramids meet at each vertex.

## Vertex coordinates[edit | edit source]

Its vertex coordinates are the same as those of the general of its army, the hexacosichoron.
